Latency Issues when matchmaking

I’m having latency issues that are sometimes causing a constant stutter or fully disconnecting me. (Sometimes SC2 will fully crash my internet which seems very odd).

Hey, Apache! Thank you for including a WinMTR test! The problem is starting on the home network and there is a consistent 12-13% loss on the home network.

This might be caused by mitigation since the test doesn’t appear to be losing any packets. At the end of the test, it shows the same values as the home network. It may help to the the following:

  • Close background applications.

  • Reset network devices.

  • If wireless, optimize the connection by using a wired connection. If wired is not an option, try checking if the connection supports dual band, then switch between 2.4Ghz and the 5Ghz bands.

  • There’s settings within the router/modem that helps mitigate or prioritize the home network traffic, so one device or connection type could have priority over another that can cause packet (data) loss or latency spikes, resulting in a disconnection.

    Check for the following settings in the router and disable any that are enabled:

    • QoS (Quality of Service)
    • WMM (Wireless Multimedia)
    • UPnP (Universal Plug and Play)

    The settings for these can vary from depending on the device model. It’s not something that we help with directly because the settings and locations can vary. The router manufacturer or Internet Service Provider (if the router/modem was provided by them) can help look for these settings.

If the problem continues, you’ll want to contact the ISP to take a look at the connection test and see if there may be something else causing the issue.
